A kit for assembly of a modular joint prosthesis includes at least two stem-body elements sized for insertion into the shank of the bone and at least two head members sized to replace one bearing surface of the joint. Each stem-body element includes a collar to be superimposed on the resected level of the bone, said collar providing a male taper at its outer diameter. Each head member is formed with an inner surface providing a corresponding female taper for receiving the male taper of each stem-body element. The engagement of the female taper on the male taper defines a space above the collar and a passageway extending from the space between the head member and the collar and provides a mechanical connection between the head and the stem-body element.
